Syncplay client version : 1.4.0 OS: 4.10.11-1-Arch Linux
Syncplay Debug logs: https://pastebin.com/raw/Qn9gUA3e
Description:
When using the flag --msg-module in mpv.conf the client isn't able to detect that a file has been loaded. Tested by commenting out msg-module flag and Syncplay works as expected.
#msg-module # prepend module name to log messages
msg-color # color log messages on terminal
Edit: This isn't really an issue but I did a bunch of troubleshooting since I wasn't able to load the file with my mpv.conf vs running it with no conf and narrowed down to this flag.
